In systems typified by software defined radio, existing flows for run-time FPGA reconfiguration limit resource efficiency when constructing a variety of datapaths. Our approach allocates a sandbox region in which modules from a library can be flexibly placed and interconnected. An efficient run-time framework makes use of lightweight placement and routing techniques to respond on-demand to application requests. Compile time tools automate the task of adding interface wrappers to modules, insulating the designer from reconfiguration details.
